In this work, a theoretical study on elastic electron‐NH x ( x = 1,2,3) collisions in the low‐energy range is presented. More specifically, calculated elastic differential, integral, and momentum transfer cross‐sections are reported in the (1–30)‐eV energy range. An optical potential composed of static, exchange, and correlation–polarization contributions is used to represent the electron‐target interaction whereas the iterative Schwinger variational method and the method of continued fractions are used to solve the scattering equations. Comparison of the calculated cross‐sections for electron scattering by these targets shows that the results are very similar to each other at higher incident energies. This similarity indicates that the interaction between the scattering electron and the central Nitrogen is dominant. © 2008 Wiley Periodicals, Inc. Int J Quantum Chem, 2008
